NCLR150 - 150Amp Fuse

NCLR150 - 150Amp Fuse

Looking for an NCLR150 150-amp fuse? This Class R fuse is designed for applications that require time-delay, current-limiting protection, and a high interrupting rating. The NCLR150 is rated 150 amps with a 200 kA A.I.C. at 600 VAC and comes in a cartridge-style, non-indicating design. Its time-delay characteristic accommodates brief current surges that may occur during normal equipment operation while still protecting against sustained overcurrent conditions. It measures 7.13 inches high by 1.54 inches wide and 1.54 inches deep, so checking it against the space and specifications of an existing installation is straightforward. For maintenance, replacement, or equipment-matching applications, the NCLR150 gives you a practical combination of 150A capacity, Class R construction, current-limiting performance, and a 600 VAC rating. As with any fuse replacement, check the electrical ratings and dimensions against the equipment requirements before installation.

Key Features and Benefits

• 150 amp rating for equipment and circuits requiring a 150A fuse.
• 200 kA A.I.C. at 600 VAC provides a high interrupting capacity.
• Time-delay design accommodates temporary current surges while protecting against sustained overcurrent conditions.
• Current-limiting Class R construction helps limit fault current when the fuse is properly applied.
• Cartridge style provides a familiar configuration for compatible Class R applications.
• Non-indicating design without a built-in blown-fuse indicator.
• At 7.13" × 1.54" × 1.54", its dimensions are easy to compare with the existing fuse and equipment requirements.

Material Compliance and Certifications

Specific agency certifications and material-compliance information were not included in the available product specifications. Do not assume certifications or compliance standards. If your application requires a particular listing, certification, or material standard, confirm that requirement using the appropriate product documentation before installation.

Where It Works Best

The NCLR150 Class R fuse is intended for compatible electrical applications that require a 150 amp, time-delay, current-limiting fuse with a high interrupting capacity. It suits commercial and industrial equipment where brief current surges can occur during normal operation and where the specified 200 kA A.I.C. at 600 VAC is required.

You can also use it to replace an existing NCLR150, provided the electrical requirements and physical dimensions match. Don't rely on amperage alone- verify the fuse class, voltage, A.I.C. rating, time-delay characteristic, dimensions, and equipment requirements before replacing it. Qualified electrical personnel should perform installation and select the fuse.
